WINFIELD HANCOCK YOST, OF MONTREAL, QUEBEC, CANADA, ASSIGNOR 0F ONE-HALFTO OTTO WILLIAM MEISSNER, OF WESTMOUNT, CANADA.

MEANS FOR FILING COAL AND THE LIKE.

To all whom it may concern:

Be it known that I, WINFIELD HANoooK Yos'r, of the city of Montreal,Province of Quebec, Canada, have invented certain new and usefulImprovements in Means for Piling Coal and the Like; and I do herebydeclare that the following is a full, clear, and exact description ofthe same.

-Hy invention relates particularly to the stocking of loose commodities,such as coal, gravel, grain and the like in piles and it has for itsobject to facilitate the work and economize the power required, therebyreducing the cost of stocking commodities of this nature.

The invention may be said to consist, broadly, of means whereby thepotential energy of the commodity being piled is converted into dynamicforce and applied to a device for delivering the commodity.

For full comprehension, however of my invention reference must be had tothe accompanying drawings forming a part of this specification, in whichsimilar reference characters indicate the same parts, and wherein Figure1 is a side elevation of my improved piling apparatus; Fig. 2 is atransverse vertical sectional view taken on line A A Fig. 1; Fig. 3 is adetail enlarged side elevation of portions of the lead and permanenttrack illustrating the variable rail joint; Fig. 4 is a plan view ofsuch variable rail joint; and Fig. 5 is a plan View of a portion of ayard tracked to accommodate my invention; Figs. 6 and 7 are detailtransverse vertical sectional views taken on lines X X and Y Y,respectively Fig. 2.

The preferred embodiment of my invention comprises a trestle I) which isof usual construction, such trestle having a lead 0 at one end for thecars to mount and descend, while a plurality of wheels d adapted to runalong tracks 6 laid permanently in the yard where the commodity is to bepiled, enable the trestle to be moved bodily s'idewise.

The trestle is preferably made in sections and an inclined wall 9extends in sections from end to end of the said trestle, each section ofthe latter containing a section of the wall which is located between theusual bents 70, while sheathing m is carried upon the opposite sides ofsuch bents, and a vertical wall 12 forms an upward continuation of theillclined wall. These wall sections and sheath- Specification of LettersPatent.

ing extend from the top of the lead to within a short distance of thelower end thereof.

The sheathing m is extended as at 25 to form a housing for the wheels(Z, the purpose of such sheathing including the portion acting as thehousing being to facilitate the withdrawal of the trestle from the pileand at the same time prevent clogging of the wheels.

Stringers 39 extend along the trestle and support the track 1 upon whichare run the cars to be emptied and carrying the commodity to be piled,while a footboard s for various uses is mounted at the top of thevertical wall a.

A series of blocks t clamped to the rail by bolts a or otherwise securedat any desired place along the rails of the permanent ground tracks,retain the trestle against movement.

A pair of swinging tracks 41 and w leading from and forming part of andpivoted to the ends of a pair of spurs m and 3 are slidably andpivotally connected to the end of the track upon the movable lead andeach of these swinging tracks is adapted to move to a limited extentwith the movable lead thus enabling the cars to be run onto the trestlewhatever its position may be along the yard.

Spring yokes 50 yieldingly connect together the ends of the rails at thefree end of the lead, and a lever 51 enables these ends to be lifted,while the contacting sides ofthese rails and the rails of the swingingtracks are sheared off. This structural feature forms the slidingconnection above mentioned.

Operation: Blocks 2 similar to t are secured at points a short distancein advance of the trestle which is previously moved to the end of theyard faced by the inclined wall, the movable lead accompanying it orbeing independently moved to proper position to register with the otherspur. The loaded cars are then run upon the trestle and discharged,their contents falling into the spaces inclosed by the inclined wallsections and the sheathing, the weight of a large proportion of the massthus precipitated leaning upon the inclined wall-sections g. WVhen thepile has attained the desired height the portion thereof leaning uponthe wall sections will possess considerable potential energy which, whenthe blocks t have i so been removed, is converted into dynamic force bythe inclined wall sections and applied thereby to the trestle which isthus moved until itcomes into contact with the blocks 2, such operationbeing repeated as required. The trestle and lead constitute the meanswhereby the commodity is delivcred and the inclined wall-sections themeans whereby the potential energy of the commodity is converted intodynamic force and appliedto the trestle and its lead, or if desired theinclined wall of the lead can be dispensed with and such lead movedindependently.

W hat I claim is as tollows:-

1. The combination with a movable support adapted to hav a conveyer forcarrying a loose commodity run thereon for the pur pose of having itsload discharged in a pile, of a member carried by the support inposition to have a portion of the piled commodity bear thcreagainst andadapted to transmit the potential energy of the pile to the support forthe purpose of moving the v latter.

2. The combination with a movable trestle adapted to have cars forcarrying a loose commodity run thereon for the purpose of having theircontents discharged in a pile, of a member carried by the trestle inposition to have a portion of the piled commodity bear thereagainst andadapted to transmit the potential energy of the pile to the trestle forthe purpose of moving the latter.

The combination with a wheeled trestle for temporarily supporting a caradapted to be run thereon to discharge the load upon or against suchtrestle and to be run therefrom, of means for facilitating thewithdrawal of the trestle from the piled commodity.

4. The combination with a wheeled trestle for temporarily supporting acar adapted to be run thereon discharged and run therefrom, of a housingfor the trestle wheels.

7 5. The combination with a wheeled trestle for temporarily supporting acar adapted to be run thereon discharge and run therefrom,

ot sheathing tor the portions of the trestle liable to be inclosed bythe piled material.

6. The combination with a movable trestle adapted to have cars forcarrying a loose commodity run thereon for the purpose of having theircontents discharged in a pile, of displaceable means for securing thetrestle against movement, and a member carried by the trestle inposition to have a portion of the piled commodity bear thereagainst andadapted to transmit the potential energy of the pile to the trestle forthe purpose of moving the latter when the means for securing the same isdisplaced.

7. The combination with a movable trestle adapted to have cars forcarrying a loose 8. The combination with a movable trestle adapted tohave cars for carrying a loose commodity run thereon for the purpose ofhaving their contents discharged in a pile,

o-f displaceable means for securing the trestle against movement, and aninclined wall carried by the trestle transversely to the direction ofits movement in position to have a portion of the piled commodity bearthereon and adapted to transmit the potential energy of the pile to thetrestle for the purpose of moving the latter when the means for securingthe same is displaced.

9. The combination with a track, or a. wheeled trestle thereon havingtrack sup porting stringers, and vertical members supporting suchstringers, and the said trestle being adapted to have cars containing aloose commodity run thereon for the purpose oi being discharged, anddisplaceable means for securing the trestle against movement along thetrack, of wall sections carried by the trestle between such verticalmembers and extending transversely to the said permanent track, andsheathing upon the opposite sides of the said vertical members, the wallsections being adapted to have a portion of the piled commodity bearthereon for the purpose of converting the potential energy of thebearing portion of the pile into dynamic force and causing such force totend to move the trestle.

10. The combination with a movable trestle bearing a track, of aninclined member bearing a track, and means etl'ecting a slidingconnection between the tracks upon the said parts.

11. The combination with a track, and a movable trestle bearing a track,and an inclined wall upon such trestle, of an inclined movable memberconstituting a iead for enabling cars to be elevated to the trestle suchmember bearing a track and an inclined wall for the purpose set forth.

12. The combination with a wheeled trestle of a wall extendingtransversely to the direction of travel of the said trestle.

In testimony whereof, Ihave signed my name to this specification, in thepresence of two subscribing witnesses.
